  "abstract": "目的揭示坡面采取不同靶向保护性耕作方式对典型黑土坡耕地土壤总磷（TP）、有效磷（Olsen-P）和磷组分分布的影响机制，为减少坡面磷素流失，提高土壤磷有效性等提供科技支撑。方法基于典型黑土坡耕地2 a田间耕作试验，研究常规耕作（CK，当地传统耕作方式）、坡中靶向免耕秸秆覆盖（NTm）、坡中靶向免耕秸秆覆盖加生物炭（NTm+b）、坡上和坡中同时靶向免耕秸秆覆盖处理（NTtm）、坡中靶向免耕秸秆覆盖加生物炭结合坡上靶向免耕秸秆覆盖（NTtm+b）对玉米播种前和成熟期全坡面土壤TP、Olsen-P和磷组分分布和流失的影响。结果与CK处理相比，NTm和NTm+b措施降低坡中位置活性有机磷和中等活性有机磷含量，但因提高坡中位置活性无机磷、中等活性无机磷含量而提高Olsen-P含量，提高坡中位置稳定磷含量而提高TP含量。同样，NTtm和NTtm+b措施降低活性有机磷和中等活性有机磷含量，因提高坡上和坡中位置活性无机磷、中等活性无机磷含量而提高Olsen-P含量，提高坡上和坡中位置稳定磷含量而提高TP含量。所有处理坡下则因外部输入减少而降低所有磷组分、TP和Olsen-P含量。从整个坡面来看，NTtm处理显著提高全坡面的TPstock和Olsen-Pstock（p<0.05）；而NTtm+b处理只显著提高全坡面的Olsen-Pstock（p<0.05）。结论在坡上和坡中实施靶向保护性耕作可以增加土壤磷储量，并且通过增加活性磷组分提高土壤磷的有效性，其中NTtm是黑土坡耕地减少磷流失、提高磷有效性和储量的优选耕作措施。",
